For all the sexiness featured in and around the new movie [movie id="427166"]"Burlesque"[/movie] — the beautiful women, suggestive dances, saucy songs — the film's high-profile cast endured a few not-so-sexy moments in the process of making the song-and-dance flick.

"You're under hot lights, you're sweating," first-time actress Christina Aguilera told us at the Hollywood premiere Monday. "There's moments where you're not always feeling so cute, things aren't always in the right place. Things pinch, the dancing makes your toes hurt unbelievably after hours and hours and hours," Aguilera, who just received a star on the Hollywood Walk of Fame, lamented. "After 18 hours of dancing on your feet, you're toes aren't too cute."

"There were lots of girls crying after 16 hours in high heels," Cher said. "And you're just going, 'Oh my God, I can't stand this another second.' But that was light stuff," she revealed, adding that the trade-off was a great experience and a fun movie.

"Oh I don't talk about my non-sexy moments," he joked. "Gosh, what was a non-sexy moment? I'm pretty sure me walking around with that cookie box, in my mind, is not a sexy moment," he said of a particularly suggestive scene in which Gigandet is wearing nothing but the cookie box in question.

When we suggested the smokey/smeared eyeliner his character wears from time to time might be less than appealing, he replied, "Smeared eyeliner? I don't even know what that means."

Premiere attendee Kathy Griffin didn't have any unsexy moments to share since she wasn't in the film, but we did ask her about a favorite sexy moment in her own life.

"My sexy moment is when I want to close the deal with a guy and then I say, 'Where do you live?' " she deadpanned. "That's my come-on line. It's a little direct, I admit it, but it's just 'What's your address, time's a wasting.' And it usually works."
